Auto merge of #93691 - compiler-errors:mir-tainted-by-errors, r=oli-obk
Implement `tainted_by_errors` in MIR borrowck, use it to skip CTFE Putting this up for initial review. The issue that I found is when we're evaluating a const, we're doing borrowck, but doing nothing with the fact that borrowck fails. This implements a `tainted_by_errors` field for MIR borrowck like we have in infcx, so we can use that information to return an `Err` during const eval if our const fails to borrowck. This PR needs some cleaning up. I should probably just use `Result` in more places, instead of `.expect`ing in the places I am, but I just wanted it to compile so I could see if it worked! Fixes #93646 r? `@oli-obk` feel free to reassign
